I am currently an industrial design undergrad at Pratt institute (NYC), and I am also interested in interaction design.
I would recommend reposting this question in the interaction design thread
You might want to try and connect with CG the moderator for the thread. He is also an interaction designer who started in the field as ID.
If you have any examples of what you’re working on I would be interested to hear about it. Also, how did you get into the field?
That’s why ID and IxD are closely linked. IxD can approach problems differently, but ideally an Industrial Designer will be fluent in both methods. ie. If you’re designing a product, don’t just sketch, but create storyboards that depict behavior. Be able to speak to usability heuristics, conventions, IA strategies etc.
I highly recommend all Industrial Designers read “Designing Interactions” by Bill Moggridge. Bill was one of the first Industrial Designers to recognize the growing gulf between designing for hardware and software:
Yes, about Face 3 is a thick one. You might want to read ‘The Inmates are Running the Asylum: Why High Tech Products Drive Us Crazy’. It does not discuss interaction design itself but it shows why it is important from a business stand of view. This could help you ‘sell’ interaction design in your job.
